1 Claim.

This invention relates to improvements in a combination siphon and pump.

An object of this invention is to provide a device capable of being used as a siphon or a toilet bowl pump, said device including a tubular pump chamber with exible tubes extending therefrom, one of which is adapted to empty in a toilet bowl waste stack while the other is adapted to deliver water thereto from the toilet bowl, said device being provided with an improved means of fixing it in place within the toilet bowl.

Ancillary objects and features of importance will become apparent in the following description of the illustrated form of the invention.

In the drawings:

Figure 1 is a longitudinal sectional View of a typical toilet bowl having the device disposed therein for operation;

Figure 2 is an elevational View of the device, portions being broken away in section to illustrate detail of construction;

Figure 3 is a fragmentary sectional view of the structure of Figure 2, showing a second arrangement of parts insofar as valve setting is concerned;

Figure 4 is a fragmentary perspective view of a part of the device;

Figure 5 is largely a schematic view of a portion of the device showing its adaptation as a siphon of general utility; and,

Figure 6 is a fragmentary sectional View of the lower part of the device showing the position of the elements when the device is used as a Siphon.

The necessity for clearing the bowl of water is two fold. First, it facilitates cleaning the bowl. Cleaning the under water surface of a toilet bowl has long been a problem. Many special preparations are on the market to take care of this problem. My invention overcomes the difficulty of 'cleaning this underwater surface by simply removing the water. ,'Ihus, one can clean the entire bowl at one cleaning, and with any simple cleanser. Secondly, in cold climates, toilets have to be protected against freezing when the family goes away for a day or so. The water is difficult to remove, hence the need for a device such as mine.

In :carrying out the invention, there is provided a bulbous member IIJ adapted for manual operation. An inner tube I2 is in communication therewith and extends downwardly into an outer tube or sleeve I4. The inner tube is provided with an opening I6 and also defines a tubular pumping chamber I8. The sleeve I4 has two openings therein, one of which is provided with the fitting 20 while the other is provided with the fitting 22. The 'conduit 24, preferably flexible, is attached to the fitting 2Il` while the conduit 26 is attached to the fitting 22.

A large suctionk cup 28 having a 'seat 30 defined by and formed by the upwardly extending lip 32, is disposed at the bottom of the sleeve I4, the lower end of this sleeve seating in the seat 30. The suction of the suction cup 28 is to provide an anchorage for the device, as disclosed in Figure 1 or as disclosed in Figure 5. In Figure 1 the device is disposed in the toilet bowl 36 and is in condition for operation to empty the toilet. A weight 38 is provided on one end of the tube 26 and there is a discharge opening 40 in the side of the tube 26 adjacent the weight.

The precise operation of the device in this connection is as follows: the inner tube I2 is rotated with respect to the outer tube or sleeve I4 until the pin 42 strikes one end of the horizontal slot 44 formed in the sleeve I4. At this time, the opening I6 of the inner tube is in alignment with the fitting 28. Accordingly, by squeezing the bulbous member IIJ and allowing it to return to its original condition, liquid will be drawn through the conduit 24 into the pump chamber I8 and this liquid is used for priming the siphon. Then, the inner tube I2 is rotated with respect to the sleeve I4 until the pin 42 engages the outer end of the horizontal slot 44. At this time the opening I6 (Figure 3) will be fin communication with the fitting 22. Then the bulbous member is squeezed again forcibly pressing the liquid in the valve chamber I8 through the tube 26 for discharge through the opening 48. When the tube 26 is thoroughly primed and while still squeezing the partially emptied bulb I0, the sleeve I2 is raised so that the pin 42 slides up the Vertical slot 54 for disposition on the land 56. This permits free siphoning action from the water in the bowl through the tube 24, chamber 58 below the closed bottom of the tube I2 and the conduit 26. While the water is still flowing from the tube I2 through the conduit 26, the tube I2 is raised. This closes the port I6 and the closed bottom of the tube I2 cuts ofi all pressure from the bulb I8. The tube I2 remains filled with water while the bulb I0 remains in a partially collapsed condition. The conduit 24 is filled with water from the bowl, so that the siphoning action from the primed tube 26 draws the water from the conduit 24, filling the chamber 58 formed by the raising of the tube I2. This permits the starting of the siphoning action.

As noted in Figure l, the conduits 24 and 26 may be arranged to conduct water from the toilet bowl to the Waste stack. This may .be accomplished by siphoning action, as described, or by pumping action by lling the pumping chamber with the setting shown in Figure 2 and then discharging with the setting of the tube l2 shown in Figure 3.

In certain instances the device may be employed as a. pump or siphon of general utility, as disclosed in Figure 5. y Liquid is being drawn from the beaker for deposit in the elementl which may be a drain, receptacle or any other selected device.

First the device is fastened, as by the suction cup 28. The conduits are arranged as shown in Figure 5 and the tube I2 turned so that the opening I6 aligns with the conduit 2l. The bulb l0 is squeezed and relaxed to draw liquid from the receptacle 50 into the chamber i8, thus priming the conduit 24. Then the tube l2 is lifted to draw more liquid into the chamber 58 from the conduit 24 for ow through the conduit 26.

Thesiphon may be out oifby lowering the tube vl2 and may be again started by raising. .the tube l2 without further priming.

`I-.Iffwine described the invention, what is claimed @f5 116W i5.:

A pump comprising a vertical sleeve having diametrically opposite ports .tllere'n1,A .conduits communicating with the ports, a vacuum cup on the lower end of said sleeve, a barrel rotatably and slidably mounted in the sleeve and operable to raised and lowered positions, said barrel when in lowered position closing the ports and when in raised position opening said ports, said barrel having a port therein selectively registerable with the diametrically opposite 4ports when said barrel in lowered position, a collapsible bulb onerotivel-y connected to theibarrel, and coacting means on the sleeve and barrel for controlling the rotary `and sliding movements of said barrel.
